How should i prepare for the SAT.

<p>Hi i'm a Homeschooler from Australia. I am currently in 10th grade and i have decided that i will sitting the SAT as an alternative for our exam we have here (because it's rubbish). I would like to do engineering which requires and SAT of around 1840 for our universities. However i would preferably like to get a score of 2100 because that would get me into any course i want as well a full scholarship. My question is how should i go about preparing for the SAT? I have purchased a few books that have practice test and tips. I will be sitting the exam early in 12th grade and then again if i'm not happy with my score.<br>
In short i'm in 10th grade and want some tips on how i should prepare for the sat.
BTW our universities don't care about GPA's, interviews and subject test.
Thanks</p>
